PlayStation2's CPU

[nikko]

Recently, I am playing Final Fantasy XII. The graphic is just simply amazing. I remember when I was moding my PS2 (yes, I mod it myself; will I ever do that again? NO) I saw the PS2 CPU; I even liked the CPU appearance.

Anyway, I decide to put the CPU into my online museum. I was browsing thru the data and then I was amazed how advanced PS2 was in 1999. (and only US$299.99 per machine)

BTW, I keep thinking about whether I should do an English version of my CPU collections pages, but it seems like nothing more I can add the description; English CPU Information is widely avaliable everywhere. I could just copy/paste all the info but, then, what's the point of doing an English version then.

SONY COMPUTER ENTERTAINMENT ANNOUNCES WORLD¡¦S FASTEST 128 Bit CPU "EMOTION ENGINE" FOR THE NEXT GENERATION PLAYSTATION

TOKYO, March 2, 1999 -- Sony Computer Entertainment Inc. is pleased to announce the co-development with Toshiba Corp. of the 128 bit CPU ("EE", or "Emotion Engine") for use in the next generation of PlayStation. In order to process massive multi-media information at the fastest possible speeds, data bus, cache memory as well as all registers are 128 bits; this is integrated on a single chip LSI together with the state of the art 0.18 micron process technology. The development of a full 128-bit CPU is the first of its kind in the world.

According to MicroDesign Resources, the processor can handle 6.2 gigaflops at 300MHz. A single gigaflop equals one billion floating-point operations per second. MDR says that makes the chip two times faster than a 733-MHz Pentium III and 15 times faster than a 400-MHz Celeron at handling tasks like full-motion video. For the statistics-minded, the processor can handle 75 million 3D transformations per second, and can render images at 2.4 billion pixels per second. In 2003 the US National Center for Supercomputing Applications used 70 PS2s to build a supercomputer capable of half a trillion operations per second.

They cost more then $299 as they were sold at a loss in order to make money on games and accessories.

Still impressive.

I have a PS2 v3 main board with this chip (and the others of course). My problem is that it was made in quite a few versions (3 or so different processes) and I just couldn't identify mine

The markings on the chip:

Is there any way to tell which version is this one? Thanks in advance!
